World to watch as Trump outlines his foreign policy

WASHINGTON, April 27 (Reuters) - Donald Trump will set aside his bad-boy antics on Wednesday and, with the help of a teleprompter to keep him on message, outline what his foreign policies would be if he is elected U.S. president in November, campaign aides say.

Governments alarmed at the prospect of a Trump presidency will be paying close attention. Critics have accused the Republican front-runner of bigotry and posing a danger to U.S. national security.

Many foreign policy and defense advisers say his views are worrying, mingling isolationism and protectionism, with calls to force U.S. allies to pay more for their defense and proposals to impose punitive tariffs on some imported goods.

"Part of what I'm saying is we love our country and we love our allies, but our allies can no longer be taking advantage of this country," Trump told reporters on Tuesday night in a speech preview.

He said he would focus on nuclear weapons as the single biggest threat in the world today. "I'm probably the last on the trigger," Trump told ABC's "Good Morning America" on Wednesday, citing his opposition to the Iraq war.

Trump, 69, said he agreed with President Barack Obama's decision to send an additional 250 U.S. Special Forces into Syria but would not have made the decision public. "I would send them in quietly because right now they have a target on their back," he told CNN.

He also said his speech would focus on the economics of foreign policy "because we're getting killed on economics."

The billionaire businessman promises to temporarily ban Muslims from entering the United States and to build a wall to block off Mexico.

His policies are popular with many voters who want change, but foreign policy elites are concerned.

"It's a perfect storm of isolationism, muscular nationalism, with a dash of pragmatism and realism," said Aaron David Miller, a foreign policy scholar who has worked in Republican and Democratic administrations.

The speech at noon (1600 GMT) in a Washington hotel will address issues including global trade, economic and national security policies as well as building up the U.S. military, his campaign said.

It is expected to be the first in a series of policy speeches meant to show that Trump, fresh off a sweep of five Northeastern state nominating contests on Tuesday, is worthy of the White House even though he never held public office.

"He needs to show that he has the substance, the depth of knowledge and the vision to be the American commander in chief," said Steve Schmidt, who was 2008 Republican nominee John McCain's campaign manager.

Trump's biggest backer in Washington, Republican U.S. Senator Jeff Sessions, said the candidate would offer "a more restrained foreign policy, a more realistic foreign policy that counts the cost not only now but in the months and years to come."

VIEWS POPULAR AT HOME

Driving much of Trump's rhetoric is what he feels is the need to ease the U.S. financial burden overseas, focus more on nation-building at home and make sure American companies pay a price for outsourcing jobs to countries where labor is cheaper.

"His views are reckless and dangerous, but that doesn't necessarily mean that they're unpopular," said Lanhee Chen, who advised former 2016 Republican candidate Marco Rubio and 2012 Republican nominee Mitt Romney. "That's part of the challenge."

Trump has declared the North Atlantic Treaty Organization obsolete and said European countries should be pulling more of their weight in the post-World War Two alliance.

Obama has for years urged Europeans to bolster their defense spending to help NATO, but unlike Trump has never said the alliance needs to be reconfigured.

In a joint paper published this month, national security and regional experts at the Center for Strategic and International Studies rejected Trump's position on overseas bases.

"The United States gets the better end of the deal from its forward deterrent posture than any other nation, and its value outweighs its current costs," Kathleen Hicks, Michael Green and Heather Conley wrote in Foreign Policy magazine.

Trump says South Korea and Japan rely too much on the U.S. military presence there and should be paying for it.

He also has said they might need to develop nuclear programs to counter North Korea's atomic belligerence, prompting Obama to say Trump was ill-informed on international relations.

Former U.S. Navy chief Admiral Jonathan Greenert, a former commander of the Japan-based U.S. Seventh Fleet, said it was not accurate to suggest Japan and South Korea get a free ride from the United States, since both countries are each subsidizing their U.S. base presence by billions of dollars a year.

In the Middle East, Trump has said he would use U.S. forces to "knock the hell out of ISIS," an acronym for Islamic State. He would get the forces out quickly and create safe havens for Syrian refugees so they do not come to the United States.

Dennis Ross, who was a Middle East adviser to both Democratic and Republican administrations, said Trump's rhetoric suggested his worldview was something of a throwback to political thinking that drew a significant following among Americans before the U.S. entry into World War Two.

"I don't think that anyone would feel they could count on the United States," Ross said. (Additional reporting by David Brunnstrom, Matt Spetalnick, Warren Strobel and Richard Cowan, Susan Heavey, Doina Chiacu; Editing by Richard Valdmanis, Howard Goller, Peter Cooney and Lisa Von Ahn)
